Electrically small receive-only resonant antennas with wideband performance for FM radio reception in mobile phones
TL;DR: In this article, an antenna concept for FM radio reception in mobile phones is proposed and evaluated by resonating a loop or monopole radiator with a shunt element and connecting the antenna to a high-impedance low noise amplifier, an equivalent antenna efficiency of −24±3 dB is achieved over the entire band of 88- 108 MHz despite having high Q gain characteristics and without using control voltages for frequency tuning.

Analysis of Vertical Loop Antenna and Its Wide and Flat Variant Performance in Wearable Use
TL;DR: An optimized antenna prototype for a wearable use is manufactured and its performance is verified by measurements that show that the decreased height and the increased width of the antenna increase the bandwidth potential of the inherently narrowband loop and increase its directivity.
